Title: Improvements in or relating to ovens for bread making and similar purposes
IPC: A21B1/46
Filed: 1923-11-20
Abstract: 227,575. Oviedo, F. F. Nov. 20, 1923. Bakers' ovens.-In a bakers' oven wherein the material to be baked is carried through the oven by means of endless chains, the driving of the chains is effected by means of screwed shafts T, either directly, as shown in Fig. 1, or through toothed wheels R', R, as shown in Fig. 17. In the first case the chain is composed of links D, each having at one end an apertured ring a, Fig. 6, and at the other apertured forks e, whilst in the second case the chain comprises short links of the form shown in Fig. 13, the links being coupled in each case by bronze sleeves fitting tightly in the rings or bosses and loosely in the forks. The rods s which carry the tray supports pass through the coupling-sleeves and are located against longitudinal movement therein by screw caps or by the sleeves of the tray supports. These rods extend to engage guides W and, in the form shown in Fig. 1, are driven by the shafts T. In either case the conveyer may be provided with any suitable number of intermediate runs, and in the second case, the shafts T may be vertically disposed. Means for charging the oven may comprise an ovening table M which receives the trays B from the conveyer V and a hinged peel P, Fig. 3, which normally assumes the position shown and holds open the oven door C by means of brackets O. When, however, a tray is fed to the peel by rotating the handle shown in Fig. 1, the peel assumes the horizontal position and the door closes until a carrier removes the tray. The carriers are of the form shown in Fig. 8, and as each approaches the peel P it engages a stop t and takes up an inclined position, thereby discharging the baked material into a shoot S and the tray into a space 0, from which it is discharged by the downward movement of a hinged counterweighted member M. After the discharge of the tray, the stop t passes through a recess in the carrier arm, so that the latter resumes its normal position prior to removing a tray from the peel P. The apparatus may be mounted on a motor vehicle, the conveyers then being driven from the engine.

Abstract: 1,029,578. Hydraulic jacks. CHRISTIANI & NIELSEN Ltd. and G. PERSICKE. Oct. 5, 1964 [July 25, 1963], No. 29595/63. Addition to 992,405. Heading B8J. The stroke of a jack as described in the parent Specification is limited by a valve having a duct 44 normally closed by a ball 47 on a seat 48 against which it is loaded by a spring 49. A rod 50 slidably disposed in a bore 46 engages the cylinder 14 in a recess 51 in the wall so disposed that in the inner position of the piston 13 the rod 50 engages the deepest part of the recess 51. Pressure fluid introduced into the chamber 18 actuates the jack and augments the spring pressure to seat the ball 47 until extension of the piston 13 causes the rod 50 to ride out of the recess and force the ball 47 off seat 48 so that the pressure fluid can exhaust from the chamber 18 through the duct 44, thus preventing the pressure in the chamber 18 from increasing further and thereby maintaining the piston 13 in a given jacking position. The duct 44 and associated valve may alternatively be disposed in the outer cylinder wall, with the recess 51 in the piston wall (not shown).

Title: Improvements relating to the production of unsaturated aldehydes
Inventor: GASSON EDWARD JAMES
IPC: C07C45/35
Filed: 1958-09-17
Abstract: In a process for the preparation of unsaturated aldehydes by the oxidation of olefines in the gaseous phase with molecular oxygen in the presence of selenium and materials containing compounds of heavy metals, selenium is recovered from the gaseous reaction mixture by contacting the exit gases with gas adsorption charcoal at a temperature of at least 40 DEG C.  The mixture may then be passed into a second catalytic reactor containing molybdic oxide, with ammonia and molecular oxygen for the production of nitriles.  The reaction mixture may be cooled to between 20 and 100 DEG C. to reduce the selenium content before passage over the charcoal, preferably maintained at between 50 and 80 DEG C.  The charcoal may be pretreated with acids such as oxalic or phosphoric and the selenium is recovered therefrom by extraction with organic solvents such as acetone, methanol, butanol, benzene or carbon tetrachloride. Examples describe the oxidation of propylene to acrolein and the removal of selenium from the exit gases with charcoal at 100 DEG C. and 61 DEG C., and the reaction of acrolein with oxygen and ammonia at 400 DEG C. in the presence of molybdic oxide to yield acrylonitrile. Specification 625,330 also is referred to.

Abstract: 902,321. Fluid-pressure brakes. BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Aug. 31, 1960 [Oct. 5, 1959], No. 30061/60. Class 103 (1). [Also in Group XXIX] Upon admitting control fluid to a cavity 26 via a port 18 during operation of a valve, e.g. a brake valve, a diaphragm 30 is lowered to seat a hollow exhaust closure 36 on the upper end of another valve closure 42 so disconnecting an exhaust port 20 from a compressed air delivery cavity 24. Continued movement of the closure 36 displaces the closure 42 from a seat 43 to connect an inlet cavity 22 with the cavity 24 whereby fluid flows from both a port 16 to the device to be actuated, and a port 60 to a cavity 35 beneath the diaphragm 30; when the delivery pressure acting on the various areas exposed thereto equals the control pressure on the upper side of the diaphragm the whole assembly is elevated by light springs 41, 46 until both closures lap. The closure 42 is stepped and slides in chambers 52, 58, the former being open to atmosphere and the latter connected to the cavity 35. Balancing is effected by making the upper part 50 of the closure 42 the same diameter as the seat 43, and the annular area of the closure 42, around the closure 36, equal to that of the lower end 56 thereof; alternatively the upper side of the diaphragm is of greater area than that of lower side, including the area of the closure exposed to the delivery pressure, and the end 56 is larger than the annular area of the closure 42. In a modification, the diaphragm 30 is replaced by a piston, and the balancing is effected in chamber 52 instead of chamber 58, which balancing chamber opens to the sealing surface of the closure 42 via passages through the larger diameter part 50 thereof.

Abstract: 192,210. Jeffrey, G. Nov. 11, 1921. Roundabouts. - An amusement device comprises means whereby a car is automatically given a forward and a backward movement in a sinuous or a direct course and is also adapted to rotate about a pivot by which it is attached to its base. The device is shown in plan in Fig. 1 and in elevation in Fig. 2. The car 13, of the tub tvpe, is pivoted on a base 8 by means of a spindle 15 which is eccentric to the axis of the car, so that the car rotates about the spindle by centrifugal force when the device is in operation. The base 8 is mounted on wheels 9 and is connected to a fixed centre 11 by a slotted arm 12, thus permitting a limited radial movement. One of the wheels 9<1> acts as a guiding wheel and is moved by an arm 20 which engages a cam 21 driven from the shaft 25 of the motor 26. The movement of the wheel 9<1> causes the vehicle to move in a sinuous path as it revolves around the centre pin 11. The vehicle is actuated by two driving-wheels 27, 28 mounted beneath the base 8. These wheels are rotated in opposite directions and are mounted in bearings which are pivoted on a shaft 33 and are upheld by springs to keep the wheels out of contact with the floor. Cams 35, 36 on a shaft 37 bring the wheels alternately in contact with the floor, so that the vehicle is driven first in one direction and then in the opposite direction about the central pivot 11. A third wheel 53 is periodically raised by a cam 55, actuated by a ratchet mechanism, to make contact with the bottom of the car, and thus rotate it about the spindle 15. The cam 21 may be shaped to steer the car in a path of any desired configuration.
